Explanation:

Opal is a gel of high commercial value and beauty that is formed in rock cracks when temperatures are extremely low and the rocks are made of iron, magnesium, sandstone and basalt. The formation of this gel is very rare, which makes it very valuable and provides a lot of money for those who find it, as the question above says. An evidence that supports this statement is the existence of tourists who spend hours looking for opals, in the regions where it can be formed. These tourists do this so that, if they find an opal, they can sell it and have a lot of money for retirement.
